Start-up and Function Test:
After connection of the charging converter according to the description, a function test can be executed.
1.
Start the vehicle or switch on ignition (Kl.15).
-
The charging converter will be activated and starts with 10 % of the maximum charging capacity.
-
The LEDs "Power”, "Battery I”, "Main Charging” will be lighting, LED "Current” is lighting dimly.
2.
Increase the speed of the vehicle to increase the voltage at the starter battery until it exceeds the adjusted value for
the increase of the charging capacity.
-
The charging capacity will be increased and is raised to the maximum value or to the required value of the
charging characteristic line, if the board battery is already full.
-
The lighting intensity of the LED "Current" will be reduced or increased depending on the charging current.
Function of the Power Control for Starter Battery and Generator:
The charging converter is activated by the control input "Kl.15 / D+", and will be deactivated automatically if the motor is
switched-off. It starts with 10 % of its achievable charging capacity.
The setting of the two slide switches "Input Type" on the unit's rear (see table 2) now affects the further load of the
starter battery circuit supplying current to the charging converter.
After the motor start, also the starter battery shall be charged immediately and its starting capacity shall be maintained.
Therefore, the gradual increase of the charging capacity for the board battery will not be effected before the voltage
value "increase of the charging capacity" of the starter battery is reached.
In case of strong load on the starter circuit due to many large consumer loads and the starter battery’s voltage drops
below the value "reduction of the charging capacity", such as during motor idling, there will be a gradual reduction of the
charging capacity for the battery Board I, to relieve the starter circuit. But the minimum charging capacity will always be
10 % of the achievable charging capacity.
If the voltage drops below the "Switching off threshold charging converter" for 30 sec., the charging converter will be
switched-off automatically. As soon as the voltage exceeds the threshold "increase of the charging capacity", the
converter will be switched-on, and the capacity will be increased gradually until the required (maximum) charging
capacity is reached.
A reduction of the charging capacity by more than 30 % due to insufficient input voltage of the generator will be indicated
by a flashing LED "Batt. II". The LED will turn off, as soon as the input voltage is sufficient or when the power requirement
had dropped anyway due to a charged board battery "I".
Pilot Lamps:
"Battery Full"
(Board battery fully charged,
green
):
•
If it is on:
Battery has been charged to 100 %, trickle charge U2 and storage charge U3, finished.
•
If it is flashing: Main charging process is effected in the charging phase U1, indication of charging state of
approx. 90 % (short flashing), gradual increase to 100 % (long flashing).
•
Off:
Main charging process is still effected in the charging phase I.
"Main Charging"
(Main charging board battery,
yellow
):
•
If it is on:
Main charging process is effected in the phase I and after that in the charging phase U1.
•
Off:
Trickle charge U2, U3.
•
If it is flashing: 1. Battery temperature sensor is not connected!
2. External battery overvoltage
>15 V
delay 20 sec.,
Automatic reset
<13.2 V (depending on type),
delay 30 sec.
"Current"
(Charging Current,
red
):
•
The lighting intensity will be
reduced or increased depending on the supplied charging current
.
Turns off < 0.2 A.
"Battery I" (
Board battery,
yellow
):
•
If it is on:
Control and charging of board battery "I".
•
Off:
Board battery "I" is separated from the charging converter (safety switch).
•
If it is flashing: Battery protection: Abnormal battery temperature < -20 °C or > 50 °C. Switchover to low safety
charging voltage and half of the max. charging current. Automatic return at normal
temperatures.
•
Turns off
Is lighting longer with turns off shortly approx. every 2 sec.: Battery temperature below 0 °C, the
shortly:
charging current can be reduced for battery protection, and longer charging times can be
expected, if the battery is discharged.
